Manchester City have condemned homophobic chants from some of their own supporters during Sunday's FA Cup tie with Chelsea at the Etihad Stadium.

Pep Guardiola's side eased to a 4-0 victory to eliminate Graham Potter's side and set up a fourth-round tie with Premier League leaders Arsenal, should Mikel Arteta's side defeat Oxford United on Monday.

A section of home fans could be heard chanting "Chelsea rent boys", which in January 2022 was defined as a hate crime by the Crown Prosecution Service.

City confirmed after the match they are looking into the matter along with the Football Association (FA).

"Manchester City strongly condemns the behaviour of a minority of fans who engaged in discriminatory chanting at today's match," a club statement read.

"We are proud to celebrate inclusivity in football and ask all fans to join us in creating a positive environment and atmosphere, where everyone is welcomed, accepted and has a fantastic matchday experience."

Sunday's incident is the third of its kind in the past week, with the FA also investigating chants used by Nottingham Forest fans during their 1-1 Premier League draw against Chelsea, and by Manchester United supporters during their FA Cup win against Everton.

An FA spokesperson said: "We strongly condemn the use of the term 'rent boy' and we are determined to drive it out of our game. We continue to work closely with the Crown Prosecution Service, as well as the UK Football Policing Unit, in relation to the use of this term.

"Part of our work in this area has been to provide the relevant authorities with impact statements from LGBTQ+ supporters, detailing how chants of this nature affects their experience and feeling of inclusion at football matches, so that a clearer stance and understanding on the chant can be established.

"We stand firmly against all forms of discrimination and we are striving to ensure our game is a safe environment for all, which truly embraces diversity and challenges hateful conduct both on and off the pitch."
